A man and his 19-year-old daughter struggle to survive raging fires in Australia.

This week we visit New South Wales, Australia, where the worst bushfires in recent history are attacking multiple towns, overwhelming firefighters and trapping tourists at a lakefront caravan park. The Philippines is usually resilient to natural disasters, but a 6.4-magnitude earthquake catches everyone off-guard — including a family who are trapped in a swimming pool. In England, it's a fight for survival, as a group of cavers attempt to rescue their colleague from the flooded section of an active cave. And in Kansas, two tornado chasers intercept a terrifying twister.
